One or more of the burners is configured to impart heat and turbulence to the molten material, producing a turbulent molten material comprising a plurality of bubbles suspended in the molten material, the bubbles comprising at least some of the combustion products, and optionally other gas species introduced by the burners. The molten material and bubbles are drawn through a bushing fluidly connected to a forehearth to produce a glass fiber comprising a plurality of interior regions substantially devoid of glass.

摘要： A precious metal structure which has an internal gas permeable membrane is described herein for a glass manufacturing vessel configured to have molten glass flow therein. The internal gas permeable membrane can be supplied with an atmosphere of gas (or gases) to control the flux of hydrogen into our out of the molten glass or otherwise improve the production of the molten glass. In this manner, the undesirable detrimental reactions that can occur at the interface of the molten glass and precious metal interface which can cause defects in the molten glass such as bubbles or solid inclusions can be stopped or at least substantially reduced.

摘要： An oblong conduit (13) for conditioning molten glass is disclosed. The wall (23) of the conduit is composed of a precious metal, e.g., a platinum-rhodium alloy, and can be equipped with precious metal tabs (29) for supporting the upper surface (25) of the wall so as to reduce sag of that surface at such times as the conduit is at an elevated temperature and is not filled with glass. The precious metal tabs (29) can be received in channels (31) formed in a refractory support structure (27). The refractory support structure (27) can be a laminate of two layers (33,35), where one of the layers (33) has a smaller grain structure than the other layer (35), the layers being held together by an adhesive (37).

摘要： Forehearths that create a substantially homogeneous temperature to molten glass forming materials across the end position are provided. A gas cavity, a weir, a refractory block, or a heating element in the forehearth may be utilized to reduce a temperature gradient of molten glass forming materials across the end position. Reducing the temperature difference of the molten glass forming material across the end position permits for improved chemical and physical properties of the glass fibers and the end products formed from the glass fibers. In addition, a reduction in the temperature gradient across the end position produces a more homogenous glass fiber and glass product. Further, a reduction in the shear break rate occurs when the molten glass forming material has a temperature that is substantially the same across the end position, which results in a reduction in the breakage of glass fibers and an increase in manufacturing efficiency.

摘要： The present inventions relate to the means of production of high-silicate inorganic fibers of natural acidic rock minerals and also to products manufactured of said fibers, namely: continuous, staple fibers and scaly particles. In each variant of the M dacite or rhyodacite, granite or rhyolite, or a rock comprising mostly sand with silicon oxide content equal or exceeding 73% are used as a rock. The present inventions aim at proposing the means for producing inorganic fibers of natural acidic rock minerals and also the products manufactured of said fibers, namely: continuous, staple and coarse fibers and fine scaly particles having increased strength, corrosion and temperature resistance. This objective is attained by creating conditions for removing foreign inclusions, having high melting and boiling temperatures, from the melt by way of using rocks with higher silicon oxide (SiO2) content and, therefore, higher melting points, as raw materials. This enables removal of most of foreign inclusions from the melted rock to the atmosphere.

摘要： A method and apparatus for the conditioning and homogenization of glass melts that are transported in flow channels with a vertical central longitudinal plane and side walls, by using the effect of alternating cross-section changes in the flow direction and stirrers with vertical stirrer shafts installed in the flow direction. The glass melt is transported through at least one flow channel, in which cross-section changes on both sides are created by several consecutive protrusions installed in the flow direction. The protrusions are directed towards the central longitudinal plane and on their upstream sides and downstream sides have wall areas that are arranged at such an angle to the central longitudinal plane, that no right-angled or acute-angled corners are created in the flow channel. The stirrers are installed between consecutive downstream sides and the upstream sides of the protrusions.

摘要： A molten glass supply device is provided, which can solve unavoidable problems for high viscosity characteristics in connection with the conventional molten glass supply device for high viscosity glass. Such problems include improperly high heating cost caused by excessive heat radiation in a melting furnace, reduction in the grade of products deriving from an excess amount of an erosion foreign material and reduction in the product yield. High viscosity molten glass having a property in which a temperature at which the molten glass exhibits a viscosity of 1000 poise is 1350° C. or higher is supplied to a forming device through a melting furnace, a distribution portion in communication with the outlet of the melting furnace, and a plurality of branch paths branching from the distribution portion. In the branch paths, distribution resistance providing portions that provide distribution resistance to molten glass passed through the branch paths are provided. The supply pressure of the molten glass is equalized when molten glass is distributed from the distribution portion to the branch paths. The distribution portion has a shallower bottom than the melting furnace.
